Have had copper coil for 5 years and am late 2 weeks

[tm123]

I have now had the copper coil for 5 years, I am pretty sure mine last for 10 years...

In the last few months I have been extremely late on my period, 2-3 weeks, however always with some sort of sign of it coming- the usual cramps etc.

This month I am over 2 weeks late and no sign of it, I am wondering if this is normal? Or could it be that my coil was a 5 year one and is affecting my body now?

Did a test- it was negative.

Has anyone had the same problems?

Thanks
